Signal Circuit Inspection

Check for open in signal harness.
1. Measure resistance between terminals 1 of sensor harness connector and 10 of the PCM harness connector.
  Specification: Approx. 0Ω
2. Is resistance within the specification?
  YES
  - Go to next step as below.
  NO
  - Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check for short to ground in signal harness.
1. Measure resistance between terminal 1 of sensor harness connector and chassis ground.
  Specification: Infinite
2. Is resistance within the specification?
  YES
  - Go to next step as below.
  NO
  - Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Check for short to power in signal harness
1. Ignition "ON" & Engine "OFF".
2. Measure voltage between terminals 1 of sensor harness connector and chassis ground.
  Specification: Approx. 0V
3. Is voltage within the specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
